It's October and that means it is Halloween time at Pleasure Island and the amusement park has changed to reflect that, the rides are replaced with Halloween style attractions, where you can go to inside a Haunted House, a Crypt, a graveyard, a witch's house. Anything that is related to Halloween. This sounds like quite an exciting place, this Pleasure Island sounds more like a Paradise than ever. But you don't know it but you are in Great Danger when you are on this island.
You didn't know about it while you were on the boat with the other boys and you still don't know about it now, even though you are currently on the Island with all of the other boys, but the longer you on this island, the more you are affected by a curse. Since it is Halloween Time on the Island, you can get turned into anything that is related to halloween, like a black cat, a tailed werewolf, a tailed vampire bat, a ghost with a tail instead of legs, anything halloween related. Right now you are a human male boy, but if you succumb to Pleasure Island's Magic and Curse, your body will get affected, slowly but surely and more and more.
First you will grow a turn into one of the species that is related to halloween, then you will grow a tail of that species just above your Human Boy Anus, then the next step is that you grow fur all over your body that you look like a hairy human. Then your face will stretch into a muzzle, your ears into whatever halloween creature you are becoming then your hands, and feet will become paws, unless you happen to be a tailed vampire bat, in that case your arms and hands become wings, or a ghost then your legs becomes a ghostly tail. What happens after this is that your Clothes get destroyed leaving you naked, then your Testicles will turn into Ovaries. Your Scrotum will recede into a vulva and vagina, your Penis wither into a clitoris. Your navel or belly button, or bellybutton and your private parts including your, vagina and anus will turn into that of a Female Halloween Creature of whatever you become.
After all of these happen, you will gradually lose your Human Mind. If it progresses a little after that, then you will be stuck like this forever. And if progresses too much after that, then you will be unable to escape and you will collapse, faint, pass out, lose consciousness, and be trapped in Halloween Town Forever.
Also once you are seen with a Halloween Creature tail just above your human boy anus meaning the changes are starting to happen to you, the Pleasure Island Staff and guards will try to kidnap you, if they succeed, You will gradually, slowly, but surely turn into a naked female tailed halloween creature and be stuck in halloween town ferever..
If you escape the island and you get back to your home when you start changing you might turn fully back as a fully clothed human boy then again you might not. You might be a fully human boy, or a fully human boy but naked, or you might be a mostly human boy with just a tail on your butt just above your human boy anus, a Furry or ghostly Human boy with a Tail, a Human boy with a Halloween creature Face, fur and Tail, etc. Or you might even be a naked Female Halloween creature with your Private parts exposed, a Feral Halloween creature with your Private Parts exposed, etc.
